I needed to design a desk calendar for a customer and started doing a few experiments. We are printing 500 of these for HIQ in Nelspruit. I thought about doing a few for myself as well. So the experimentation had to do with the paper grammage.

The tent fold calendar assembled
You can design your own Calendar for your desk by doing the following. You will need a printer that can print borderless on A4 or you will need to make your calendar a little smaller. 170g card works but is rather light and flimsy, 300g card works best. The problem with 300g card is that most printers are not able to handle that thickness board.

Design Layout
Basically the tent fold calendar is an A4 page with 3 folds and glued at the one end. I made mine by doing the design in four parts. two 105mm panels, a 20mm glue lip and the balance of the card as the third panel.
I did a 6 month calendar on either side and surrounded them by graphics, including logos. I then added all the public holidays and a 2010 calender to the bottom panel. You could leave this blank but I figured a calendar for the following year and a list of public holidays and school terms would be more useful.
I printed this on 170g photo paper, cut and folded them. As you can see they work. The ones we are having done by the printers will be on 300g board.
